CARBOY PACKAGE CONSTRUCTION Filed Aug. 12. 1948 2 Sheets-Sheet 2 ATTORNEY Patented July 1l, 1950 cursor memos coNsrnUc'noN Richard W. Lahey, New Rochelle, N. Y., r to American Cyanamld Compararv New York, N. Y., a corporation of Maine Application Amst 12, 1948, Serial No. 43,8'57 1 Claim. (Cl. 217-52) The present invention relates to improvements in boxed carboys, that is, crates or cases Within which is located a frangible container, usually a bottle, ordinarily used in the shipping of liquid material.

In such boxed carboys, it is customary to provide cushions of one kind or another between the bottle and the box to absorb shocks and to prevent breakage. A considerable amount of work has been done to arrive at a construction combination which will increase the life or the Apackage as a whole and prevent undue breakage of the bottle. Y

Perhaps the best type of cushioning members are blocks of virgin cork having a. high capacity to absorb shocks, slow recoil and high age-resisting abilities, all of said properties remaining substantially unchanged at temperatures between F. and 100 F. Cast or laminated blocks of unvulcanized, reclaimed rubber are also suitable.A

and various other cushioning materials well known in the art may also be used.

It has heretofore been proposed to provide a cushion carrying carrier with a spacer or shim either wedge shaped or not, loosely tongued and grooved, between the box corner post and the cushion carrier. Under ordinary circumstances this is a very satisfactory combination. However, it all too frequently happers that when the boxed carboy is given a radial shock, the cushion adjacent the corner of the box receiving the shock is compressed to such an extent that the spacing element at the opposite corner actually leaves its groove so that on the rebound, the spacer does not reseat itself in the groove. As a result, the entire cushioning assembly in that corner of the box is thrown askew and rendered ineilective.

The .principal object of the present invention is to devise a mechanism whereby the spacing members between the corner post and the cushion carriers Iare so arranged that they cannot be displaced from their proper position.

Other objects and advantages will appear as the description proceeds.

To this end, the invention contemplates a boxed carboy comprising a box and a bottle therein with a series of cushions between the box and the bottle, a cushion carrier, a box corner post, means for forcing separation of the corner .post and the cushion carrier to thereby compress the cushion, said separation means being dovetailed into undercut grooves in both the cushion carrier and the corner post. Thus regardless of the amount of temporary shift the bottle might have, the corner post separation means and cushion carrier will always remain in their proper location.

The invention further contemplates the construction, combination and arrangement of parts more fully hereinafter shown and described in the accompanying drawings inwhich:

Fig. l is a sectional plan view through a packing of the present invention; y i

Fig. 2 is a sectionalelevation along the line 2 2 oi Fig. l;

Fig. 3 is a sectional view along the line 8-8 o! Fig. l;

Fig. 4 is a perspective view of a cushion carrier, and

Fig. 5 is a rear view of the cushion carrier oi' Fig. li.

Referring now with particularity to the embodiments illustrated, a box or casing is shown generally at i consisting of four sides and a bottom with hand holes 2 and skids 3 all of which are oi usual construction.

Within each corner of the box is a substantie.ily4V triangular corner post l having a vertical and undercut groove s therein for a purpose to be more fully hereinafter described.

Seated on the bottom of the box are cross pieces t and l carrying cushions a upon which the bottom o the bottle rests. It is preferred that the cushions 8 are made of virgin cork which normally has the properties above enumerated. It is preferred that these bottom cushions i engage the bottle bottom at an area including definite curvature as shown in Fig. 3 as this makes for eiectiveness and tends to prevent lateral displacement under shock.

The bottle is shown generally at 9 and may be of any desired conguration.

Between the bottle and the box, there are located an upper and lower set of cushions ill and il respectively. Each of these cushions is secured to a cushion carrier l2 in any desired manner as by means of cement or the like. It is preferred that the plane of the area of contact between the cushion and the cushion carrier be at an angle to the vertical so that the cushions i0 and ii likewise engage the bottle surtacevat an angle. This makes the imaginary lines of compression of the top and bottom series of cushions at an angle to each other so that they intersect when extended.

The rear face of each cushion carrier I2 is provided with an undercut groove i3, the said groove being substantially o! the same extent as similar groove 5 inthe corner post I.

A spacing member Il is opposltely dovetailed into the undercut groove 5 of the corner post and the undercut groove I3 of the cushion carrier. It is to be understood that each spacing or sepa.-

- 3 ration member Il is of a vertical/extent sumcient to engage both an upper and a lower cushion carrier. These members I4 may be either shims or wedges.

Spacer strips I5 may be used to join the upper and lower cushion carrier.

A top I6 having an aperture therein may be used to secure the bottle in the box with suitable neck-protecting devices as is usual 'in the art It is to be noted that in this type of construction where the boxed carboy receives a shock in the direction of one of its corners, there is a tendency to highly compress the cushion in that corner with the consequence that the opposite cushion and/or its cushion carrier is also free to move in the direction of shock. Unless, therefore, the separation member Il is physically restricted in the grooves in the corner post and the cushion carrier, there is every tendency for it to slip out of the grooves. When, therefore. the bottle rebounds, the separation member does not always reseat itself in its grooves and as a consequence is rendered completely ineffective. However, in the present construction due to the fact that the separation member is actually dovetailed into both the corner post and cushion carrier,'this objectionable action is positively prevented. Thus a highly satsfactory form of construction is provided.

Again it is to be noted that while the .separation member I4 is dovetailed into the grooves 5 and i3, yet the parts do not fit tightly into the under-` cut portions with the result that they are permitted to have a slight rocking movement; The spacers I5, however, limit the extent of this.

rocking. Permitting this slight rock is advan` tageous in that while the parts cannot be accidentally displaced, they are permitted a certain freedom of movement which makes for 'a not too rigid resistance to the movement of the bottle under shock.

That the cushion carriers as above described are of the iloating variety is also highly desirable in that if the cushions are not adjusted exactly right when intially placed in position, they may find their proper location in the course of time,

' stricter! when extended.

making their adjustment automatic partcularly .as the bottle settles.

While the separation members I4 vare preferably of uniform width in a direction between the corner post and the cushion carrier, the invention contemplates that they may also be slightly wedge shaped. This permitsA the upper set of cushions to be put under a, compression greater than the lower set which has been found to inhibit the tendency of the bottle to jump upwardly upon impact due to liquidl surge within thebottle. v

While the invention has been described with particularreference to specic embodiments, it istobeunderstoodthatitisnottobelimited thereto but is to be construed broadly and resolely by the scope of the appended claim. I claim:

A boxed carboy comprising a box and a bottle therein, a triangular corner post at each corner of the box containing a vertical groove, a pair of cushion carriers located generally at each corner f the box and spaced from the corner past by means of a wedging element, the wedging element being dovetailed into undercut grooves in one pair of the. cushion carriers and a corner tied together, a cushion on each cushion carrier, the plane oi the face of each carrier in contact with its cushion being at an angle to the vertical, the-top portion of each top cushion andthe bottom portion of each bottom cushion being under a compression greater than that of the remainder of those cushions, the imaginary lines of pressure onv the upper and lower cushions intersecting RICHARD w.
